To all whom it may concern: 7

Be it known that I, SVANIIORDEN, a c1t1 zen of the United States,res1dn1g at Cranston. in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in the Artof forming and Affixing Tips to Corset and Shoe Laces, of which the following is a specification.

My invention relates to the art of aflixing metal tips to corsetand'shoe-laces and 7 consists of improvemcntsin the blank from type of blank applied to-the lacing in the which the tip is for-med, and in theniethod of applying thesame to the lace. One object of my improvement is to provide as a new-artide of. manufacture a novelform; of metal blank that] can be produced at a low cost and which may beapplied to the lacejjby a simple'method of rolling it therearound.

My improvedmethod of applying the tip to. the lace al'so effects a more secure joinder of theitip with the cord or, braid, while alsotending to cheapenthe costof manufacture,

improve the finish and enhance the orna-.

mentalappearancejof the completed artich. 7

The manner and-means'for carrying out these improvements are 'fully described in the following specification illustrated by the accompanying drawings, in which like reference characters designate like, parts.

In the; drawings Y Fig. 1. is a perspective view showingv one type of myimproved tip-blank;

shown and described in detail in my U. S. Letters Patent No. 1,348,660, dated August 3, 1920. Referring to Figs. 6, 7, 8 and 9 of the present drawings, 2 designates the base of the movable die D, and C the opposite, fixed die which is cut away on its underside at 3 to allow the forward end of the die D to slide beneat 1 i. The overhanging portion d of the fixed die C is undercut on its forward end to form a beveled face 5 which is continued in a concaved recess 6'terrninating in a sharp, prow-like edge 7 which merges into the upper surface of the base 2 of the die I). The base-plate2 the die D is formed with an upsxinding, curved ledge or shoulder 8 which is shaped to conform to the contour of the tip to be produced and which cooperates with the concaved recess 6 on thefront of the lined die C in clinching the tip around the lace, see 9. Referring to Fig. 6, the top of the baseplate 2 is formed with a rest ngular block or key-piece 10 adapted to serve as a holdingmeans and guide for the die D which Slices thereon. The die D is cut away at 'ts center to form two opposite, parallel le 1l11 which straddle the sides of the i and slide thereon. The die D is held in place on its base 2 by means of'a flat plate 12 fastened to the top of the block or hey-piece 1G and overhanging the sides thereof to bear against the legs 11-11 of the die. The topplate 12 is fastened to the block 10 by inei s of dowel-pins 13-13 and a bolt-"1 L which reaches down through the base-plate 2 to secure the latter to the support (not herein shown) on which the movable die is mounted. 'The belt 11 is illustrated in section in Fig. 2,

to render the drawing clem'er, as is also the bolt 15 which fastens the fired die C to its support.

Extending acrossthe recess between the legs 11-11 of the die D is a bow-shaped spring 16 which bears against the forward end of the block 10 on tlie lyise-nlate 2. he spring 16 tends to slide the die D forward on its base 2, and the movement of the die limited-by stop-pin 17 proiecti j down wardly from the top-plate 12in an en larged hole 18 at the front of the die. The forward end of the die D is beveled off on the top and undercut at thebottorn to provide an overhanging curved. lip 19. The concaved under face ofthe lip 19 is forined concentric with the upstanding, curved shoulder or ledge 8 on the base-plate 2 and registers therewith to form a half-circle when the die D is forced back into its retracted position as shown in Fig. 9. The retraction of the die D is effected as it upper beveled face meets the correspondingly beveled under face 5 of the fixed die C when the two dies are carried together to clinch the tip around the lace? is this action is completed the curved faces on the dies come into register to form a complete circle. Normally, however, with the two dies separated to receive the blank B to be operated upon, the die D will be held by the sprin 16 in its forward position with its curved lip 119 advanced beyond the shoulder S on the base-plate 2. lnthis way he forward edge of the die D serves as an abutment or ledge 20, see Figs. 7 and 8, which over hangs the edge of the shoulder 8 on the plate 2 and clamps down the side of the blank B to hold it from lifting up out of position until the die D is withdrawn from over its It will be noted from referen-s-e to Fig. 6 that the opposite undercut workingfaces 19 and 6 of the dies D and (l and the upstanding ledge 8 of the'ba'seplate 2 are inclined slightly toward each other in a horizontal plane to adapt them to conform to the tapered sides of the blank 13, shown in j 1, which is for pointed tips. l vhen, however, a straight tip is to be applied to the lacing the working-faces of the dies are made parallel to adapt them to operateon the edges of therectangular blank 13 illustrated in Fig. 2.

Fastened toone s'ide of the diel) by means of a screw 24 is a vertical plate 25 which serves as a stop or limit for engaging the end of the blank 13 to locate itin position in setting it in place on the base-plate 2. be-

tween the workingfaces of the dies. E22 tending forwardly from the topplate 12 and reaching down across the beveled front face of the die D is a spring-arm 26 which is fastened in place by a screw 27. ,The forward end of the arm 27 is'forrned with f0rklike tines or fingers 2Swhich are curled upwardly at their entremities. The fingers 28 are adapted to bear, against: the sideof the cord or lacin L as the movable die D slides toward the med die Cto'carry the cord over into position and hold it in place to be received wit in the edge of the blank B when the latter is rolled around it asshown in Figs. *4 and S. The tines Or fingers 28 enter grooves 29 in the fixed dieC as the die D moves toward the latter, -tl16 'l')Cl3l3OIl1 of the grooves being inclined upwardly as shown by dotted lines in Fig. 6 to lift the spring arm 27 out of the way as the working-faces of the dies come into register.

The method of-operation of the dies in forming the tip and allixingit to the lacing is follows: With the dies in open relation, as illustrated in Fig. 6, the blank B is laid flat on the top of the plate 2 with its end against the st0p-plate 25. When the. die

of flat sheet-metal having its longitudinal edges bent at right-angles to the plane of the strip; holding the under side of the blank fiat against a rest by clamping down one of its edges; and applying pressure on the opposite edge of the blank to roll it around the lace and clinch it in place thereon. V

3. An improved method of forming tips and aflixing the same to corsetand shoe-laces consisting in bending up a blank from a flat strip of sheetmetal to form a narrow rightangled flange extending along its side; holding the under side of the blank flat against a rest by clamping down one of its marginal edges; applying the end of the lace to the top of the blank and holding it thereagainst;

and'exerting pressure beneath the bent up side of the blank to roll it around the lace.

4:. An improved method of forming tips and 'afiixing the same to corsetand shoe-' along its sides ;'holding the under side of the strip flat on a rest by pressure against one of its upturned edges; applying pressure beneath the opposite upturned edge of the blank to roll it around the lace; and finally clinching the rolled over. sides ot the blank together at their joinder.

5. An improved method of forming tips for corsetand Shoelaces and applying the same thereto consisting in bending up a blank from sheet-metal to form a troughlike strip having right-angled flanges eX- n testimony whereof I atlin my signature.
